Title: Improvements in or relating to lift or hoist arrangements
IPC: B66C15/04
Filed: 1933-02-22
Abstract: 418,665. Control of two motors. EXPRESS LIFT CO., Ltd., and STEVENS, J. W., Greycoat Street, Westminster. Feb. 22, 1933, No. 5475. [Class 38 (iii).] Traversing towers carrying lifts are provided with electrical interlocking-means so that no two towers can approach within a predetermined distance without the traversing-drive being stopped and preferably also the brake applied, the arrangement preferably also ensuring that both towers cannot be driven simultaneously towards each other so as to approach one another at high speed. Pairs of contacts 40-47 spaced on the runway for the towers are closed by cams fixed on the towers, the one tower bridging the upper row of contacts and the other the lower row. The drive is stopped by establishing a connection between the main leads 48, 49 and this is effected by the crossconnections between the upper and lower line of contacts whenever the two towers approach within a distance equal to twice the spacing of adjacent contacts in the same row. The circuit of the main lead 48 includes switches 50, 52 and magnetizing coils 51, 53 as shown. These switches are only closed while the corresponding motor is running, and the connection of the leads 48, 49 passes a current through the closed switch of the pair and energizes the corresponding coil 51 or 53 to open one or other of two switches 54, 55. These latter switches break the circuit of the main controllers for actuating the towers in one direction, for example the switch 54 may prevent the main controller for the one tower which has been moving towards the left from traversing it further towards the left, while the switch 55 prevents the other main controller from traversing the other tower further towards the right. For preventing the towers being actuated so as to move towards one another at high speed, the main controllers may actuate secondary closing switches in the act of starting the motors and these secondary switches may be interlocked so that they cannot be closed for actuating the one tower in any particularly direction unless the other one is at rest or moving in the opposite direction.

Title: Improvements in the manufacture of artificial filaments and other products containing organic derivatives of cellulose
IPC: D01F2/28
Filed: 1934-02-21
Abstract: Artificial filaments, ribbons, and other products having a basis of cellulose acetate or other organic derivative of cellulose are obtained by a wet spinning process in which the shaped materials are coagulated in a medium containing a solvent or plasticizer for the cellulose derivative, and the wet materials are stretched and then allowed to shrink under the action of the solvent or plasticizer. Preferably the coagulating medium contains a high concentration of solvent or plasticizer. Diacetone alcohol, glycol mono-acetate, methyl glycol mono-acetate, ethyl lactate, acetone, dioxane, methylene - ethylene ether, methylene chloride, ethylene chloride, methyl alcohol, ethyl alcohol, methyl acetate, and ethyl acetate, are specified solvents.  Cellulose derivatives of normal, low, or high viscosity characteristics may be used.  Stretching and shrinking may take place in the coagulating bath or after emergence but under the action of coagulating medium carried by the filaments or other materials.  The materials may subsequently be stretched or shrunk again, or saponified.  In an example, cellulose acetate solution is extruded into aqueous glycol mono-acetate, and the coagulated filaments pass round a stretching roller and under a second roller dipping into a bath of water.  They pass round a third roller rotating slower than the first roller so as to allow shrinkage, and then to a take-up device.  Specifications 177,868, 179,234, 207,562, 316,521, 318,468, [all in Class 2 (ii)], 340,324, 340,325, 370,430, 371,461, 380,504, 380,505, 389,823, 402,104, 402,105, 402,106, and 406,016 are referred to.
